I really think its called equipment error.
Ur sure, cause it's a vocaburlary word again
It can't be "equipment error" since part of the definition indicates "the experimenter" -- a human.

Do you have a vocab list you're working from? Or are you supposed to guess?
It was Systematic Error, but thanks for ur efforts
